为了引进适宜临湘市种植的中稻新品种,选择湖南省农业技术推广总站安排试种的中粳甬538、中粳甬4149和当地引进的两优889等3个品种以及1个国审、3个湘审品种,与当地的主种品种新两优343进行田间品比试验。结果表明:中粳甬538、中粳甬4149、Y两优7号实际产量明显高于对照,广两优1128与对照的实际产量处于同一水平,其余5个品种产量明显低于对照。中粳甬538、中粳甬4149和Y两优7号比新两优343更适宜湘北地区的气候及地理环境,可作为当地主推品种,广两优1128可作为替代品种,新两优343可继续作为当家品种种植,其余品种则建议继续试种或不推广种植。
In order to introduce new varieties of mid-season rice suitable for planting in Linxiang City, three varieties of Zhongyueyong 538, Zhongyueyong 4149 and Liangyou 889, which were locally introduced, and one national trial were selected for trial planting in Hunan Agricultural Technology Extension Station. A Xiang trial varieties, and the local main varieties Xinlianyou 343 field ratio test. The results showed that the actual yield of Zhongyouyong 538, Zhongyueyongyong 4149 and Y Liangyou 7 was significantly higher than that of the control. The actual yield of Guangliangyou 1128 was the same as that of the control, and the yield of the other five varieties was obviously lower than that of the control. Zhongyueyong 538, Zhongyiyueyong 4149 and Y Liangyou 7 were more suitable than Xinliangyou 343 for climate and geographical environment in Xiangbei. They could be used as local main push varieties. Guangliangyou 1128 could be used as an alternative variety, and Xinliangyou 343 Continue to grow as a headed species, the rest of the species is recommended to continue to test or not to promote planting.
